The information objects that the server offers in the command and monitoring direction, are linked to the controller with existing process variables, via the configuration. No change to the programming code is necessary for this. A different data model can also be created for different clients.
To reduce the communication load, a threshold filter can be enabled. Values that are outside of defined Min/Max limits are marked as invalid and will only be transferred again when they return to the valid range. No implementation by the user is necessary for this. A monitor in the SolutionCenter shows the current configuration of information objects used in the server, and the value most recently transmitted to the client.
Easy to use tools for configuration of the client and server are available in the SolutionCenter. The master is configured like a local I/O module on whose channels the information objects of the internal devices are represented in monitoring and command direction.
Existing software for sequence control and regulation does not need to be changed and will not be affected in its runtime. Thus it can be flexibly responsive to final customer requirements without changing the existing tested software for control and regulation of the substation. Through realization as a finished server with integrated update- and threshold logic, tedious replication of the protocol functions via limiting PLC-libraries, and the associated training efforts in the standard, is eliminated. Engineering and testing time can thus be reduced, and the integrated diagnostics shorten the troubleshooting in the event of malfunctions during operation. 2b1af7f3a8
